       Abstract: Based on the specimens collected from Yunnan Provinceꎬ the lichen genus Schizotrema Mangold & Lumbsch is
       reported as new to Chinaꎬ with the species Schizotrema guadeloupense (Hale) Mangold & Lumbsch. Among Graphidaceaeꎬ
       the genus is characterized by its ascomata with concentrically layered margins composed of carbonized excipular remnants of
       older hymeniaꎻ the proper exciple is fused to indistinctly freeꎬ periphysoids are usually presentꎬ and the ascospores are
       transversely septate to muriform. The species S. guadeloupense is also new to Asia. In additionꎬ notes of other five species in
       the genus are also givenꎬ with ecology and distributionꎬ and world ̄wide key to species of Schizotrema is described in the
       present paper. All these results provide basic data information for the taxonomy of the family Graphidaceae.
